Colombia is Israel’s primary coal supplier, accounting for 60 percent of all the country’s coal imports in 2023, according to S&P Global Commodities at Sea data.
Ynet news has reported that Israel has been quick to seek alternative suppliers and reportedly has “received positive responses from South Africa and Russia”, but will have to pay a higher premium on its coal imports.
“In the immediate term, they have reserves, so it’s not going to lead to energy outages, but it will have an economic impact long term, and joined by others, it will have the effect of impacting their energy production capabilities,” a Global Energy Embargo spokesperson told Middle East Eye. “If these other countries are taking action, that’s going to have a massive knock on effect.”
The coalition is now turning its attention to South Africa, where it will begin to mobilise to halt coal exports after the new government has been formed.
“We urgently call on South Africa, which provides nine percent of Israel’s coal, to follow Colombia’s lead,” the group said. t is also looking to stop crude oil exports from Brazil.)
60% of an import is pretty huge number. Israel will be able to find alternatives but it’s going to cost them.
