NewsWatch ranked the five-year greenhouse gas trends of South Korea's top 10 conglomerates, from Samsung Electronics and SK Hynix to POSCO and Korean Air. The data, sourced from the Greenhouse Gas Inventory & Research Center, shows a split: LG Electronics cut emissions 38%, Lotte Chemical dropped 23.9%, and POSCO fell below 70 million tCO2eq, while Hanwha Aerospace emissions more than quintupled and HD Hyundai Heavy Industries rose 54%. Samsung, Hyundai Motor, and GS Caltex stayed roughly flat. The article frames the report around Nepal's request for disaster recovery funds from major emitters after Himalayan glacier floods, citing IPCC cumulative emissions data. For investors and procurement teams, the useful part is the granularity: absolute totals vary widely, and the biggest names are not always the biggest emitters. POSCO remains the largest absolute source at 69.85 million tCO2eq, while Hanwha's 121,740 tCO2eq is small in volume but growing fast. Read the full piece for the year-by-year table and the companies' stated responses, including POSCO's HyREX hydrogen ironmaking plan, GS Caltex's carbon-free steam contract, and SK Hynix's HBM eco-certifications.

The Nepal framing is interesting, but the numbers here look like direct site emissions, not full lifecycle or supply chain. Hanwha Aerospace jumping 5x is real, but it is still tiny next to POSCO. Would be good to know if these include electricity purchases or just fuel burned on site. Without that, cross-company comparisons are shaky.

The accountability link is loose. Nepal asking for compensation from China, US, India is about historical emissions, while this article scores Korean firms on five-year deltas. Those are different metrics. LG cutting 38% is good, but from a low base. POSCO is still the elephant. A five-year trend does not tell you who is aligned with 2050 net zero.

Samsung and SK Hynix being flat makes sense if the grid they buy from is still coal-heavy. RE100 procurement helps, but absolute emissions only drop when the underlying grid decarbonizes. The article notes Samsung's emissions stuck despite RE100. That is the same story across Asia: corporate targets cannot outrun grid fuel mix.

Lotte Chemical and POSCO show what happens when efficiency investments and process shifts actually land. But the petrochemical slowdown is doing some of that work. A 23.9% drop in emissions is easier when production is down. Would like to see emissions per ton of output, not just totals.

Worth reading for the data table more than the Nepal hook. Korean Air says flight emissions fell 3.3% while flights increased, which is the kind of intensity metric that matters. But the ground emissions numbers in the article are a tiny slice of an airline's real footprint. Jet fuel is where the carbon is.

GS Caltex bringing in carbon-free steam and a solar PPA is useful, but 70,000 tons a year is small against 8.5 million tons of total emissions. These are pilot-scale moves. The story would be stronger if it showed what share of each company's emissions those projects actually cover.
