@giacgrassi.bsky.social is a Senior Scientific Officer at the European Commission’s Joint Research Centre (JRC). A leading expert on forests and climate, he specializes in LULUCF and greenhouse gas inventories. He is a prominent IPCC author and recipient of the 2020 Bologna Award for Sustainability.

A black and white, close-up portrait shows a man with short gray hair and dark eyes looking directly at the camera with a subtle, pleasant smile. He is wearing a light-colored blazer over a collared shirt and a dark necktie with a small, light-colored patterned design. The background is a blurred outdoor scene with leafy trees.

Chi è Lysenko, e cosa c’entra con Trump, l’IPCC e la democrazia? Ne abbiamo scritto nel Il Sole 24 Ore con il filosofo della scienza Matteo Motterlini. Uscire dall'IPCC non significa sottrarsi al riscaldamento globale, così come gettare il termometro non fa sparire la febbre.

With a mixed-results at COP30 - i.e. good intentions but no concrete plans for the “transition away from fossil fuels” - don’t give up. Let’s remember the progress made since the Paris Agreement and the options ahead of us. That’s the message of the image below

What is the contribution of land use to countries' climate pledges? 🖋️ A new paper led by Rosa Roman-Cuesta explores this question and offers a way forward. 🌲 The study finds that land use makes up a quarter of global 2030 mitigation pledges — mostly reliant on external support. rdcu.be/eydhU 1/

Land remains a blind spot in tracking progress under the Paris Agreement due to lack of data comparability

Communications Earth & Environment - Discrepancies exist between data used in countries’ greenhouse gas inventories and modelled benchmarks for the Paris agreement, according to an...

On 6–7 May 2025, a JRC-EEA workshop on Land Use Land-Use Change and Forestry (LULUCF) gathered in Ispra (IT) over 50 GHG inventory experts, scientists and policymakers. We discussed challenges in GHG reporting and the decline of forest carbon sinks in Europe. Agenda/presentations: lnkd.in/dkJNxSWE

🧐 Confused about different estimates of land-use CO2 emissions? 🌲A new paper led by David Gibbs enhances comparability between satellite-based forest carbon flux maps and National greenhouse gas inventories. ➡️ Paper: lnkd.in/dU5-bv4P ➡️ Story: bit.ly/43qX2Mv ➡️ Country-level data: bit.ly/3XvBSJf

Revised and updated geospatial monitoring of 21st century forest carbon fluxes

Abstract. Earth observation data are increasingly used to estimate the magnitude and geographic distribution of greenhouse gas (GHG) fluxes and reduce overall uncertainty in the global carbon budget, ...

This is outrageous. Stupidity at work. It’s a sign of ideological hostility to everything that involves a multilateral dialogue and cooperation. If you ignore climate change, climate change will not ignore you.
