We saw it with big tobacco, we saw it with the fossil fuels industry. When their own internal research showed the harm from their product, the defunded the research and attacked independent researchers coming to the very same conclusions.

Conditional and unconditional NDCs are there in revised NDC documents submitted. what are we modelling here ???

‘There is no money’: As carbon markets collapse, what happens to the forests they promised to protect? After it was found most offsets did not represent real carbon reductions, the money dried up. But successful schemes such as Kasigau in Kenya now face a stark future

The carbon market is not the way to do CO₂ removal (CDR). If we're serious about this, it has to be a government-led effort.

@robinlamboll.bsky.social are these pathways from AR6 database ???

When any government receives negative information about their inflated base year emissions due to improved methodologies, they should correct their course and increase mitigation efforts instead of maintaining the reduction target in the revised NDC. Here is one example from Nigeria NDC.

"Here is the graph, which is so wild, the climate scientist had to call a colleague & check it"

It is true actually! In the Global Carbon Budget we do not usually show the LUC like this, because of interannual variability & uncertainty. But it is what the data says!

A figure showing all ghg emissions rising

Global Greenhouse Gas (GHG) emissions rise again in 2024, up 2.3%.

This is our collective progress, 10 years after the Paris Agreement.

which indicator they used to make this claim "Australia is moving too fast, & faster than its peers in the OECD."

Is his pivot a result of the US political environment, or does he have some divine insight that climate scientists are missing?

Interesting climate/energy policy developments in China.

We have highlighted this point in UNEP gap report 2022 "mitigation cost estimates of least-cost
pathways disregard the economic benefits that accrue
through avoided damages and societal co-benefits of
a low-carbon transition"

Influence of individual models and studies on quantitative mitigation findings in the IPCC Sixth Assessment Report - Nature Communications The paper analyses the impact of the uneven representation of models and studies on key mitigation findings in the IPCC Sixth Assessment Report. It finds that the model with the most scenarios has a considerable influence on several findings.

New paper with @glenpeters.bsky.social in Nature Communications today. We show how models and studies with a lot of scenarios in the IPCC scenarios database have a large impact on key findings, including emissions reductions, net-zero GHG year, and coal, gas, and oil consistent with 1.5°C.

Opportunities for decentralised solar power to improve reliability, reduce emissions and avoid stranded assets - Nature Communications National grid-connected solar mini-grids can reduce electricity costs, increase reliability and reduce carbon emissions. Improvements in grid reliability carry minimal financial risk to mini-grid...

India Lowers Tax on Renewables in Steps to Fight Trump Tariffs India more than halved a tax rate on domestic sales of renewable-energy equipment, as part of a raft of measures to shore up local consumption and shield the economy from punitive US tariffs.

India more than halved a tax rate on domestic sales of renewable-energy equipment, as part of a raft of measures to shore up local consumption and shield the economy from punitive US tariffs

It’s not just fossil fuels at risk of becoming stranded — without good policies, even decentralized renewables could be left behind. We have looked at this issue in this paper.

#LowCarbon #MiniGrid assets face risk of asset stranding, with the expansion of or improvement in reliability of national grids. Good #Policy to ensure these assets can interconnect can reduce this risk, + improve reliability, #emissions and costs! Read the paper here: www.nature.com/articles/s41...

The study uses #energy system #modelling to explore different scenarios of national grid/mini-grid reliability in #India, and how under different #scenarios, national grid connected mini-grids can offer a promising solution providing clean, affordable and reliable power.

In info graphic of six IAMs

The DIAMOND project has made an important milestone: the first draft release of six open integrated assessment models (IAMs) that are emblematic in both scientific and policy processes. Now is the chance to contribute and provide feedback!

I never thought I would be spending my time explaining the scientific method to one of the most well funded research institutions in the history of humanity, but here we are.

But it was so uplifting to see so many brilliant scientists provide context to every point in this thing. You guys rock.

If you need help finishing the final products of your food-related experiments in the future, please let me know.

Graph showing: Share of non-fossil generation in India's total grid generation

India has just announced that they have reached their NDC target of 50% non-fossil electricity generation capacity share. Good to celebrate progress, but generation share is still about 25%, and has been fairly stable for several years. 1/3
