The recently published Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC-AR6) cautioned that climate change is already affecting every inhabited region of the globe, and the scale of recent changes is unprecedented on a millennial time scale. The discussions at COP26 highlighted the critical need for countries to accelerate reduction of greenhouse gas (GHG) emissions and move toward net zero in the longer term. This will require large-scale climate finance, with private capital mobilization in the trillions of dollars through sustainability-linked bonds and impact investment, as countries make the transition to low carbon economies. These initiatives will need new performance metrics that measure GHG emissions reductions.
Limited information has hindered decisionmaking
Performance measurement in this domain has been hobbled by the near-total absence of directly measured local and regional GHG data for problem diagnosis and program assessment. Consistently measured GHG estimates are scanty, and most rely on emissions parameters from engineering studies that are applied to survey-based activity measures for transport, energy production, and manufacturing. The parameters are particularly suspect for developing countries because many have been calibrated using databases and models in high-income economies.
Satellite-based data hold the key to global performance tracking
Sentinel satellites can be powerful allies, with high-resolution GHG measures now available from many platforms, including NASA’s OCO-2 and OCO-3 instruments, the European Space Agency’s METOP-A and TROPOMI (Sentinel-5P) platforms, China’s TANSAT, and the Japan Space Exploration Agency’s GOSAT and GOSAT-2.
In a recent working paper, we used new satellite data to measure and analyze CO2 emissions from over 1,000 global cities. We chose to use NASA’s OCO (Orbiting Carbon Observatory)-2, which offers open access, a long panel of consistently measured daily observations, and the highest spatial resolution among the available sources. We focused on cities with more than 500,000 people, as these localities have high concentrations of economic activity and emissions.
Our econometric model of the CO2 emitted by cities takes account of their most carbon-intensive industrial activities (power plants, steel mills, refineries, cement plants); local fires (carbon emissions from agricultural and forest burning); incomes; populations; population densities; and climate-based heating needs. After the model accounts for these factors, the regression residuals provide performance indicators that identify cities whose CO2 emissions are less than or greater than model-based expectations. This provides the first empirical scorecard of urban CO2 emissions management that is based on actual CO2 observations.
How do global cities perform?

Figure 1 shows that the performance measured by city regression residuals exhibits wide variation, both within and across regions. However, Figure 2 shows that regional patterns do differ significantly. China has a striking number of large positive residuals (indicating CO2 emissions greater than expectations), while the former Comecon countries have many large negative residuals.

Other regions with larger-than-expected residuals include East Asia & the Pacific, sub-Saharan Africa, and the Middle East & North Africa. Western Europe and India have smaller-than-expected residuals, while distributions are roughly centered around the global average for North America, Latin America & the Caribbean, and South Asia (excluding India).
Satellite sentinels are opening a new frontier for GHG performance analysis
We are optimistic that the World Bank and other institutions will expand this new approach to performance measurement using satellite-based CO2 monitoring. While our study has focused on large cities, the same model could be used in geographic settings as varied as large and small cities within regions or countries, regions within countries, or specific project areas. To provide better metrics to track progress in greenhouse gas reduction, we hope to extend this pilot initiative to an open-source, regularly updated CO2 database that will inform all global stakeholders.
Palladium One Extends High-Grade Mineralization 250m SW of Kaukua Open-Pit Resource

( ) (FRA: 7N11) (OTC: NKORF)
continues to advance its Läntinen Koillismaa (LK) platinum group element-copper-nickel property in Finland — this week announcing that initial down plunge drilling has extended mineralization 250 meters southwest of the open-pit constrained resource estimate at the Kaukua deposit.
Hole LK21-101 intersected 1.5 g/t palladium equivalent (PdEq) over 74.5 meters starting at 273 meters down hole, and returned a higher-grade 2.2 g/t PdEq over 19.6 meters.
Other high-grade intercepts included:
- Hole LK21-102, @ 3.2 g/t PdEq over 13.7 meters, within 1.6 g/t PdEq over 113.6m, with individual samples grading up to 9.6 g/t PdEq over 1m;
- Hole LK21-100, @ 3.3 g/t PdEq over 9.6m, within 1.5 g/t over 113.4m, with individual samples grading up to 5.9 g/t PdEq over 1.5m.
“The high-grade ‘Core Zone’ of the Kaukua deposit has been extended to the southwest and remains open for expansion. These are among the thickest intercepts to date within the Kaukua deposit and will add significant tonnage to our existing resource endowment,” said Palladium One’s CEO, Derrick Weyrauch, in the Nov. 23 news release.
The news from Kaukua alters the geological model, in a good way. As Palladium One explains,
Previous geological interpretations suggested that the Kaukua deposit was cut-off by a northwest trending fault, occupying a distinct magnetic low and topographic lineament. Drilling has demonstrated that the magnetic low is the result of a later cross cutting dyke (now referred to as the high-titanium gabbro dyke) and that the Kaukua deposit remains open to the south.
Resource definition drilling at Kaukua and the western half of Kaukua South (together known as the Kaukua area) is complete, with an updated NI 43-101 resource estimate scheduled for the first quarter, 2022.
While the Haukiahio trend is more copper-nickel rich, the Kaukua deposit contains mostly platinum group elements, with two-thirds of the value in palladium and platinum.
The Kaukua mineralized system is also much larger than previously understood, as evidenced by last year’s major discovery about 500m away at Kaukua South, which hosts a >4 km-long IP chargeability anomaly, of which 3.5 km had never been tested prior to Palladium One’s drilling work.
Initial drilling last year, therefore, focused on expanding known mineralization to the east of existing drill intercepts in the Kaukua South Zone, taking priority over the planned drilling to upgrade and convert the historical resource estimate at Haukiaho.
(As announced in a Sep. 7 news release, results from a 2,000m drill program at the Haukiaho Zone significantly increased this area’s resources (NI 43-101-compliant) to 32.7 million tonnes grading 1.15 g/t PdEq for 1.21 million ounces of contained PdEq. This resource update essentially doubles the resource endowment of the entire LK project, which now boasts 11 million tonnes of indicated resources grading 1.60 g/t PdEq (600,000 oz PdEq) and 44 million tonnes of inferred resources grading 1.19 g/t PdEq (1.7 million oz PdEq))
Kaukua South drilling successfully confirmed the eastern extension and the over-4 km strike length, insinuating the presence of a large-scale, shallow mineralized system with significant continuity.
Phase 2 drilling by Palladium One this year continued to return significant PGE grades and widths, including 47m at 2.3 g/t PdEq and 53m @ 2.1 g/t PdEq, and was successful in extending the strike length of the Upper Zone mineralization.
These results added to the company’s belief that it could add a significant amount of open-pit resources to the upcoming NI 43-101 resource estimate upgrade.
Last month the company announced the highest-grade hole to date at LK, which intersected 4.07 g/t PdEq over 24m within 2.08 g/t Pd_Eq over 112m, starting at 171.5m depth.
The question is not if, but by how much, the Kaukua drilling will add to the already doubled mineral resources at the LK property.
The Kaukua Zone at LK is mostly a palladium-platinum-gold play, however it may surprise readers to learn there are significant base metal values particularly at Haukiaho, where two-thirds of the zone’s value is in nickel and copper compared to Kaukua where 66% of the value is in palladium and platinum.
Indeed Haukiaho hosts some of the highest nickel grades on the LK project. At 17 km in length, the Haukiaho trend currently represents the largest continuous patch of blue-sky potential.
The latest resource estimate of 1.2 million ounces PdEq grading 1.15% g/t, comprises only 3 km of strike length; 2 km of strike extent, immediately east of the Haukiaho resource estimate, contains two significant IP chargeability anomalies with sufficient historic drilling to potentially be upgraded to inferred resources with modest additional drilling.
The remaining 12 km of the Haukiaho trend has not been drill-tested by the company, though widely spaced historic drilling has demonstrated that the trend is mineralized. This drilling provides a high level of confidence for potential additional nickel-copper resources to be delineated, Palladium One said.
Also worth noting is the fact that the Haukiaho Zone’s resource estimate contains cobalt. There is a reasonable expectation that the next resource estimate update at the Kaukua Zone where PDM is concentrating its drill program, will also contain notable values of the crucial lithium-ion battery component.
As for Palladium One’s Tyko nickel-copper project in Ontario, in a Nov. 16 project update the company says geophysical crews are on site conducting ground-based electromagnetic surveys on key areas; three new exploration permit applications have been filed for drill-testing the newly identified EM anomalies; and a fourth exploration permit application has been made to expand upon the existing Smoke Lake exploration permit, to allow for additional step-out drill pad locations.
“We eagerly await receipt of new exploration permits for Tyko so that we can get back to drilling and make additional discoveries.” said Derrick Weyrauch, President and CEO.
The project known for its high sufide nickel tenor, received the Bernie Schnieders 2020 Discovery of the Year Award, presented by the Northwestern Ontario Prospectors Association (NWOPA).
It covers approximately 24,500 hectares within the highly prospective Mid-Continent Rift nickel province, including over 7,000 hectares of the mafic-ultramafic Bulldozer intrusion, which has seen virtually no geological mapping nor exploration.
The Archean-aged mafic-ultramafic intrusion is rich in nickel, containing twice as much the battery metal as copper, and equal amounts of platinum and palladium.
According to the company, the high tenor of the sulfide minerals suggests a valuable concentrate could be produced, and that even if the sulfides are disseminated, the deposit could still be economic.
Drilling in 2020 primarily focused on the Smoke Lake target, an EM anomaly identified through geophysical surveying. Magnetic survey undertaken shortly before drilling helped to refine the anomaly, resulting in the successful discovery of massive magmatic sulfides.
The first discovery of massive sulfide mineralization at Tyko was confirmed in January, when the company announced drill intercepts from massive magmatic sulfide of up to 9.9% nickel equivalent. Subsequent drill results reported from the 2020 program were a resounding success, confirming the high-grade nature of the deposit.
A second-phase, 2,000m drill program was initiated in April to follow up on these high-grade hits. The assays to date have been excellent, including massive magmatic sulfide intercepts grading up to 10.2% nickel equivalent, demonstrating a robust mineralization spread over a distance of at least 18 km.
In addition to the high-grade Smoke Lake Zone, Palladium One believes there are new zones of nickel-copper mineralization yet to be discovered.
Preliminary results of the recently completed airborne EM survey have identified as many as four significant multi-line EM anomalies on the Tyko nickel-copper project, which further support this hypothesis.
Of particular interest are two anomalies in the Bulldozer Intrusion. These are the first EM anomalies identified in this large mafic-ultramafic intrusion and hint at potentially large tonnage targets.
Assay results from the Phase 2 drill program at Smoke Lake are pending.

Nickel, Industrial Metals Rise As China Property Optimism Returns
Base metals are on the rise after a series of positive announcements over the week has brought new optimism to China’s property sector.
On Thursday, Nickel paced gains by most industrial metals on the London Metal Exchange, rising 2.5%. As shown below, spot prices for Nickel are moving higher as inventories continue to shrink, pointing to mounting supply tightness.
“Nickel now looks to be the new game in town with stocks falling daily,” Malcolm Freeman, a director at Kingdom Futures, wrote in a note. “For now the bullish mood persists and there seems little point in going against it in the very short term.”
As global refined-nickel inventories continue to draw down, prices face volatility, trending toward gains, Huatai Futures Co. wrote in a note.
Earlier this week, iron ore futures trading in Singapore bounced back over $100/ton after reports of Chinese regulators dialing back crackdowns on the property market could soon lift steel demand and improve profitability for steelmakers. There’s also chatter the People’s Bank of China could unleash stimulus amid the economic growth slowdown in the world’s second-largest economy.
“The market has higher expectations for steel production to resume,” Huatai Futures Co. wrote in another note. Property is a leading source of industrial metal demand in the country.
Bloomberg Industrial Metals Subindex (BCOMIN) has broken out to an all-time-highs, surpassing 2007 and 2011 highs.
Positive developments appear on the macro front as the PBoC could be close to easing and Beijing dials back on regulatory crackdowns. Institutional investors are also getting in on the action as China’s high-yield bonds have had a bid this month.
Suppose the Chinese government continues to offer policy support to heal the ailing property market, which it crushed this year through regulatory crackdowns. In that case, this could mean industrial metals will rise some more, adding to inflation.
